Animals have always been used by humans in some form to satisfy their needs. However, while some people believe that animals should be treated in the same way humans are and have similar rights, others think that it is more important to use them as we desire for food and medical research.
With regard to the exploitation of animals, people believe it is acceptable for several reasons. Firstly, they think that humans are the most important beings on the planet, and everything must be done to ensure human survival. If this means experimenting on animals so that we can fight and find cures for diseases, then this takes priority over animal suffering. Furthermore, it is believed by some that animals do not feel pain or loss as humans do, so if we have to kill animals for food or other uses, then this is morally acceptable.
However, I do not believe these arguments stand up to scrutiny. To begin, it has been shown on numerous occasions by secret filming in laboratories via animal rights groups that animals feel as much pain as humans do, and they suffer when they are kept in cages for long periods. In addition, a substantial amount of animal research is done for cosmetics, not to find cures for diseases, so this is unnecessary. Finally, it has also been proven that humans can get all the nutrients and vitamins that they need from green vegetables and fruit. Therefore, again, having to kill animals for food is not an adequate argument.
To sum up, although some people argue killing animals for research and food is ethical, I would argue there is sufficient evidence to demonstrate that this is not the case, and, therefore, steps must be taken to improve the rights of animals.
